M-204G Black Commercial Gates Movement Sensor

Industry Introduction

When refering to the automatic door system, we first think of is various sensors like the microwave sensor, infrared sensor, laser sensor, etc. The most obvious difference between them is the application of different technologies to detect movement in an area and are used commonly in constructions, industrial, security, transportation systems.

However, in the automatic door field, the commonly used sensor types that microwave sensor, infrared sensor, and combined sensor.

Production Introduction

Microwave sensor is also called as radar, RF or doppler sensor, is popular used in the automatic door systems or other electronic devices, for detect the pedestrian's movement by using electro-magnetic radiation. It is able to detect motion by applying the Doppler effect and project microwaves which will bounce off surfaces and return to the sensor. It is able to measure and detect the amount of time for the signal to be reflected to the sensor which is known as echo time. It gives signal to the control board for opening the door.

Features & Advantages

1, ambient temperature influence is small
Strong anti-interferece ability. In the rain, wind, vibrationm fluorescent lamp environment, microwave sensor can still work stably.
2, Large detection range
Wide detection range to cover a large area, the max detection range is 4x2 meters can be adjusted.
3, Reduce False Alarms
Adopt intelligent optimized detection circuit, which greatly increases accuracy and makes it simple to use.

Parameter adjustment

1, When power on, please stand out of the detection range around 10S to ensure the sensor has enough time to finish the self-adjustment.
2, Switch the sensitivity adjustable knob to select different detection range:
The width of the range: 0.5-4 meters
The depth of the range: 0.4-2 meters
3, Direction adjustment: 0-90 degree(lengthways) -30 to +30(lateral)

Troubleshooting

Symptom	Cause	Method
Door&indicator lose failure	Did not get on power	Check cable connection & power supply
Door keep on closed and open	Sensor detected the movement of auto-door; Vibration of movement	1, Adjust the angle 2, Check the position 3, Adjust sensitivity
Door do not close Red indicator lose failure	1, Switch of automatic door controller lose failure 2, incorrect position 3, incorrect output of sensor	Check the switch of automatic door controller & setting of output
Door keep on moving when it rains	Sensor detected the actions of rain drops	Adopt waterproof accessories
